For years, polls have shown that about 90 percent of Americans support the labeling of foods that contain genetically modified organisms (GMO). That's about as close to a consensus as you're going to get in this country. But amazingly, in this supposed bastion of freedom and democracy we're denied the fundamental right to know what's in our food -- a right that more than 50 other nations, including China and Russia, offer their citizens.

That's China and Russia, as in the big scary authoritarian countries known for communism, corruption and rampant human rights violations. They're at least doing a better job of trying to look like they care about protecting the freedom to choose what people put in their bodies. In the U.S., it's estimated that 60-70 percent of processed food may contain some GMO, but the food is not required to be labeled. This glaring disconnect between America's purported democratic ideals and the reality of how public agencies like the Food and Drug Administration can knowingly fail its citizens might be about to crumble, says Andrew Kimbrell of the Center For Food Safety.

His organization is part of a broad coalition of groups petitioning FDA for mandatory labeling of GMO-containing foods. Hundreds of other organizations have joined the effort, including consumer advocates, farmers, concerned parents, businesses, environmentalists, food and farming organizations, and members of the health care and faith-based communities. The goal of the coalition, called Just Label It, is to collect enough citizen signatures to its petition that the FDA will have to take action. Or force President Obama to make the FDA act.

There are three reasons why Kimbrell believes that now, despite decades of undue influence of the biotech industry on FDA policy, the agency's GMO armor will crack.

"First of all, Obama promised, when he was a candidate, to impose labels," Kimbrell says, referring to a stump speech in 2008, recorded by Food Democracy Now, when the junior senator from Illinois promised to "let folks know when their food is genetically modified, because Americans have a right to know what they're buying."

"And finally," he says, "we have extra leverage because it's an election year. With 90 percent of Americans wanting this, and millions of comments coming his way, Obama can do the math."

Kimbrell blames a decades-long revolving door between the FDA and the biotech industry for it being the least responsive agency to consumer concerns. "The FDA is composed of people who will soon be back in the industry." It's been stuck this way since the early 1990s, when the FDA hired former Monsanto lawyer Michael Taylor to write the regulations, or lack thereof, for the use of a Monsanto product called recombinant Bovine Growth Hormone (rBGH), which is injected in cows to boost their milk production.

Consumer backlash was strong against these GMO hormone injections, detectable amounts of which had made it into the milk along with inordinate amounts of puss. So marketers of non-rBGH milk understandably chose to label their milk as such. Monsanto fought for 10 years to stop this labeling effort, using a litany of crafty strategies, to take away the milkman's right to point out that their product does not contain injected hormones that contain recombinant DNA. The company threw in the towel after taking the battle to the state level and failing in every attempt.

Bovine growth hormone, like every GMO crop, has failed to provide the consumer anything besides risk, says Kimbrell. "If you're a consumer, why would you buy a product that offers no benefits and potential harm? A product that only helps biotech corporations and industrial farmers, not consumers. If they came out with a product with less cholesterol, or more nutrition, greater yield, or lower cost, that would be one thing. But the whole "we're going to feed the world and the blind shall see and the lame shall walk isn't panning out."

Initial fears of GMO in food were based on the possibility of "what if?" And for the last 20 years we've all been guinea pigs in an experiment to find out. Meanwhile, the FDA's own scientists have been ignored, much like the vast majority of consumers, by the agency's higher-ups. In GMO-related litigation with the FDA in the late 1990s, the Center for Food Safety obtained some 80,000 pages of discovery, where its lawyers found that the FDA's own scientists had raised numerous, serious concerns about the possibility of toxicity, allergenicity, and other health risks posed by GMO in foods. And with good reason, says Kimbrell.

"We know that if certain peanut genes are spliced into foods like soy, it can trigger a peanut allergy in someone who eats it," he says. Allergic reactions are caused by proteins that confuse the body's immune system, Kimbrell says. "And the whole purpose of GM is to make new proteins."

The FDA, meanwhile, relies largely on an archaic, so-called organoleptic standard for determining if there are material differences among similar foods that would necessitate labels to distinguish among them. The organoleptic standard means, in essence, that if a food doesn't look, taste, smell, feel, or behave any different then they're for all intents and purposes the same and no labeling to distinguish them is required.

"Remember," says Kimbrell. "They've patented all these novel genes and proteins. You don't get to patent something unless it's new. So they're telling the patent office these things are new, and they're telling the FDA there's nothing new."

While definitive proof that GMO food can cause health problems has yet to be widely acknowledged, red flags and bits of circumstantial evidence are adding up.

Without labels, meanwhile, health officials are at a disadvantage when it comes to tracing potential GMO-related toxicity or allergic reactions. If GMO foods were labeled as such, public health workers would potentially have access to more data points with which to look for patterns and correlations. In the UK for example, where labeling is mandatory, soy allergy rates shot up after GMO soy was introduced there.

Products shouldn't have to be proven dangerous before they should be labeled, says Kimbrell, citing an industry position he often confronts. "That's not the criteria for labeling. If there's a novel product in the food it should be labeled. But we don't label things that are dangerous or potentially dangerous. We take them off the market."

Today, as protesters occupying Wall Street are demanding economic rights for the 99 percent of the population left to divide the table scraps of the rich, the 90 percent of Americans who want to know what's in their food are bringing the pressure as well. And if the perfect storm Kimbrell is predicting comes to fruition, those 90 percent will actually get their wish for public food policy that reflects the will of the general public.
